Following the reasoning of pass-by-value for libcamera::Span
parameters from 90c193f2a700("android: Modify Encoder interface") i.e.
they are easy to copy/move/construct, align the Exif parameter passing
to the encoder interface in this consistent way.

In Encoder::encode(), the |source| argument doesn't have to be a
pointer. This replaces its type, const pointer, with const
reference as the latter is preferred to the former.
libcamera::Span is cheap to construct/copy/move. We should deal
with the type as pass-by-value parameter. Therefore this also
drops the const reference in the |destination| argument.

The jpeg components are licensed under GPL-2.0-or-later. This is an
oversight and unvoluntary. License them under the LGPL-2.1-or-later as
the rest of the camera HAL implementation.

Create a Exif object with various metadata tags set, just before
the encoder starts to encode the frame. The object is passed
directly as libcamera::Span<> to make sure EXIF tags can be set
in a single place i.e. in CameraDevice and the encoder only has
the job to write the data in the final output.
